Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a 9 x 7 mm oval diamond, its soft brilliance framed by a delicate halo that seems to float above the finger. This platinum engagement ring is crafted with meticulous attention in our Williamsburg studio, where each prong is hand-finished to cradle the stone securely while maintaining a low-profile silhouette.

The halo setting amplifies the diamond’s natural fire, surrounding it with a ring of smaller lab-grown stones that shimmer with subtle complexity. The platinum band offers a cool, substantial feel, polished to a satin finish that resists everyday wear without sacrificing elegance.

Our commitment to ethical jewelry is reflected in the choice of a lab-grown diamond, combining clarity and sustainability without compromise. This ring’s comfort fit and modest height make it ideal for daily wear, easily paired with wedding bands or stacked with other favorites.

Should you need a custom size, resizing is available to ensure a perfect fit without altering the ring’s refined proportions. Each piece is inspected thoroughly before leaving the studio, promising a seamless blend of artisan craft and modern design.
